all diesels do this, especially on acceleration. In normal operation diesels run very lean (hence the great fuel consumption), on acceleration they run richer creating more particulates. You usually...

You are correct in that when the ABS system is working you should definitely NOT apply cadence braking, in your situation the ABS did not work so cadence braking was the next step to take.

Its 2AH and 4AH as in Amp Hour and its a measure of the battery capacity and not power output as Prof pointed out

Fitted to the engine. Crank bolt is too long (its what I had in the garage) so fitting with the washers is temporary until I source the correct length bolt

The dsg box does not like situations where you would normally slip the clutch (slowly pulling away or inching forward), in these scenarios its a horrible gearbox that either does nothing or goes to...

I have the birkin to scare me, for a road car I want something planted and stable at any speed. What I enjoy most about the Q7 is its overtaking ability, you see gap, tickle the pedal and before you...

I remember reading about that a while ago, seemingly a big issue is with the switchgear longevity due to arcing and contact corrosion due to switching higher current. Canbus has also removed a lot of...

the 48v is just for the blower and its there to fill in the gap to eliminate boost lag while the turbo's spool up, so you should have the throttle response of a NA petrol motor

I assume they use a...

I wish, my Q7 needs to do duty for another 2-3 years before I can consider replacing (it will be around 250k km at that point). Until this was launched I had no idea what that could be as I kinda...

someone needs to buy this now so I can upgrade in about 2 years time.

No offroading as such, but just in normal use modern TC systems are really amazing. When we left Clarens (in the rain after a week of rain and lots of rain overnight) I was bit worried about the...

why waste your time on a V6 when you can drive a V8>:D

believe me its zero ego, but 100% thrill of driving a powerful car. 8-)

Ek kan geen rede sien hoekom dit nie kan werk nie. Jy moet kyk na die gearing om die alternators teen die regte spoed te draai en seker te maak die engine het woema wanneer jy die 100a wil gebruik.

Can ran very well last year, in the last race I started having gear selection issues - suspect syncro's but there could be other damage as I'm pushing twice the power through the box that the stock...

weight of the rotating assembly has no bearing on the torque the engine produces. Energy is stored in rotating assembly so will affect how the power is delivered by smoothing out the power pulses...

replace conrod length with piston stroke and you are spot on. Stroke is governed by crank throw as explained above

nice to see a lot of people on the forum not scared of putting big mileage on their cars

I have a few of them around the house for a while now. Works very well and I can definitely recommend them.

think we are are trying to get to the same point.

gearing does not change the power delivered, kw stays fixed (ignoring any parasitic losses) - not sure what you mean by delivered kw, what changes...

because the higher the rpm the lower the torque the shaft is transmitting (see calc above)

Go open up the gearbox for say a winch, first stage gears are tiny, they run at high speed but transfer...

do not forget the impact of the gearbox on power delivery. a gearbox is a torque multiplyer

Take 100nm at 4000rpm, thats 42kw

put it through a gear ratio of 2:1 dropping the Rpm to 2000rpm, ...

torque is the capacity to work, i.e. you need 200nm to turn a shaft.
power is a measure of how quickly you can perform that work - i.e. how quickly you can turn that shaft by applying 200nm

power at the wheels matter, its irrelevant if its from an engine at 8000rpm in a low gear or 2000rpm in a high gear or from a petrol or steam engine. The only time the power source matters is if you...

sticking to the oil change intervals (60k on ours) is critical, do that you should be fine. I have heard of dsg failures, but no more than any other gearbox. Swambo’s car is now on 160k km and still...
